If a flight is set to say 500m at 300 kph and there is a small hill they will climb over it to avoid crashing into it, but i noticed at 4000m at 300 kph bombers will climb a bit whenever they are over huge hills, then dip at coast line etc. is this a bug or just a normal waypoint thing, this is where it seems to happen most. Do they sense the hill top as the altitude or the flat ground? I guess a radio altimiter would show it as it changes?
